Six charged in wake of party riot

People planning parties in Perth are being urged to advise the police after a 21st in Belmont spiralled out of control at the weekend.

Teenagers hurled bottles at police , did burnouts in cars and jumped on police vehicles as a crowd of 300 people, many of them gatecrashers, spilled out onto the streets near the party being held at a tennis club.

Six people have been charged with various offences stemming from the disturbance.

Sergeant Leisa Reynolds says police were not aware the party was being held.

"If we're aware that a party or a large party is being held, patrols can be maintained around the area," she said.

"If we see people starting to mill that aren't welcome there, police can get there before the numbers get too large."

A neighbour, Glenda Goodchild, says the party was out of control.

"We had people on our lawn, people obviously drunk or collapsing," she said.

"They went next door and banged on her door and she called out to them and said go away and they abused her. It was quite terrifying."

Another neighbour, Darren Brew, says there should be security at the parties.

"We actually heard, at one stage, a car come up and they threw a stubby at a police car," he said.

"Nobody wants to come out, obviously. There was probably easily a hundred people and you're thinking what's going to happen. It's not a good idea to be here."

The tennis club says it will no longer hire out the hall for young parties.
